SLED ATTACHMENT FOR BABY-CARRIAGES.

SPECIFICATION forming part of Letters Patent No. 527,357, dated October 9, 1894.

Application filed Mar h 22, 1894:. Serial No. 504,710- (No model- To aZZ whom it may concern:

Be it known that I, CHARLES J. BONGFELDT, a citizen of the United States, residing at East Marinette, in the county of Marinette and State of Wisconsin, have invented a new and useful Sled Attachment for Baby-Car riages, of which the following is a specification.

The invention relates to improvements in sled attachments for baby-carriages.

The object of the present invention is to provide for baby-carriages a sled-attachment of simple and inexpensive construction adapted to be readily applied to any ordinary baby-carriage, and capable of rapid adj ust. ment to enable it to be quickly brought into operative position to permit the carriage to operate as a sleigh in places where there is snow, and to enable it to be readily folded out of the way to bring the wheels into use in places where there is no snow.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings: Figure l is a perspective View of the running-gear of a baby-carriage provided with a sled-attachment constructed in accordance with this invention. Fig. 2 is a longitudinal sectional view of the same. Fig. 3 is a transverse sectional view.

Like numerals of reference indicate like parts in all the figures of the drawings.

1, 1, designate a pair of tubular runners,

which are connected with the front and rear axles 2 and 3, by pairs of links 4;, connected by clips 5, at their upper ends, with the axles, and by bearings 6, at their lower ends, with the runners. The runners, which although shown tubular, may be constructed of any desirable material, have secured to them the bearings 6, which consist of opposite perforated ears or flanges 7, and vertical rear flanges or backs 8, connecting the ears or flanges 7, and forming stops for the lower ends of the links to limit the forward swing of the sled-attachment, and to prevent the links from swinging forward past a vertical position.

The lower ends of the links are reduced to fit between the sides or flangesof the bearings, and their upper ends 9 are bifurcated to receive depending flanges 10, of the clips, which are composed of opposite recessed sec tions receiving the axlesand secured together and clamped on the axles by bolts or screws located above and below the same.

The links are connected and supported by transverse braces 11 and 12, composed of openwork, to secure strength, to lessen the quantity of material, to contribute lightness, and to present an ornamental and attractive appearance. The ends of the braces are provided with securing flanges, and at the ends of the rear braces are arranged integral rods 13, which are secured in the perforations of the adjacent links. i

The rear transverse brace is provided with perforated lugs 14, and has secured to it, by a pintle-rod 15, a fork or bifurcated portion 16, of an operating-rod 17, terminating at its upper end in a handle and passing through an eye 18, of a cross-bar19, which has its ends secured to the handles of the carriage. On the eye 18. is mounted a set-screw 20, adapted to clamp the operating rod to secure the sledattachment at the desired adjustment.

The handle 21 of the operating rod is horizontally disposed. "The sled-attachment may be readily adjusted by moving the handle up and down, and it is clamped at any desired adjustment by the set-screw. Its forward swing, or downward movement, is limited by the shoulders of the bearings 6, to prevent the sled-attachment from being forced forward too far, and to prevent the runners from working loose.

It will be seen that the sled-attachment is simple and comparatively inexpensive in construction, and that it may be readily secured to any ordinary construction of baby-carriage. It will also be seen that it may be readily adjusted to bring it into operative p0- sition to enable a baby-carriage to be used as a sleigh, and may be quicklyfolded to enable the wheels of a carriage to run over places where there is no snow.

Changes in the form, proportion, and the minor details of construction may be resorted of a carriage, ofa pair of runners, the straight links arranged in pairs and having their lower ends hingedly connected'with the runners, clips composed of opposite recessed sections and provided with depending flanges hingedly connected with the upper ends of the links said sections detachably engaging the axles of the running-gear, transverse braces connecting'the links and bracing the same, a cross-bar carried by the running-gear and arranged at the back thereof and provided with an eye and having a set-screw, and an operating rod having its lower end hingedly connected with the adjacent transverse brace, passing through said eye and provided at its upper end with a handle, substantially as described. V

2. The combination with the running-gear of a carriage, of a pair of runners provided with bearings composed of sides, and a back forming a stop, the links arranged in pairs and hinged at their lower ends between the sides of the bearings, clips arranged at the upper ends of the links, hingedly connected thereto and composed of opposite recessed sections engaging the axles, transverse braces connecting and bracing the links, a cross-bar secured to the runningear and provided with an eye and having a set-screw, and an operating rod passing through the eye and hingedly connected at its lower end to the adjacent transverse brace, substantially as described.

In testimony that I claim the foregoing as my own I have hereto afiixed my signature in 40 the presence of two Witnesses.

CHARLES J. BONGFELDT.
